What Size Compression Socks Do I Need? - FITS®

May 18, 2022

Compression socks provide vast benefits, including improved blood circulation, reduced swelling, and increased recovery after exercise. Whether you’re a nurse who works on your feet all day, an expecting mom, or an athlete, you can benefit from wearing compression socks. Compression socks are also essential for preventing Deep Vein Thrombosis (DVT) and other medical problems. Whatever your reason for choosing to wear these socks, it’s important to understand how to size compression socks. Keep reading for three simple steps to selecting the perfect fit for your compression socks.

How to Size Compression Socks for the Perfect Fit

If you’re wondering, “What size compression socks do I need?” then you’re in the right place. Sizing compression socks is key to experiencing the many benefits available to your feet and legs. If your compression socks are too tight, they could do more harm than good. For example, a sock that’s too tight could restrict blood flow to your feet and legs rather than improve blood flow. If your compression socks are too loose, you won’t experience the many benefits they have to offer. Therefore, understanding how to size compression socks is key. Fortunately, you can find the answer to your question, “What size compression socks do I need?” in three simple steps.

1. Measure Your Calf, Ankle, and Foot

The first thing you need to do is take measurements. For the most accurate measurements, take them when your legs experience the least amount of swelling (i.e., after walking). To do this, wrap measuring tape around the widest part of your calf and note the measurement. Then measure your ankle circumference at the smallest point, just above your ankle bones. Be sure to measure both legs and choose a sock size that fits the larger leg if applicable. Lastly, take note of your shoe size, as this will come in handy when selecting your sock size.

2. Consult a Compression Sock Sizing Chart

Once you know your foot and leg measurements, consult a sock size chart to determine the sock size that will provide the most comfortable and effective fit. Most manufacturers use a standard sizing system, so you should be able to find a chart that will work for any brand of sock. You can use the FITS sock size chart to learn which size of compression socks for men or compression socks for women will fit you best.

3. Ensure You Have the Perfect Fit

Once you know your size, it's important to ensure that the socks fit snugly but are not so tight that they cause discomfort. If you're unsure about the fit, it's always best to err on the side of caution and go up a size. If you're still uncertain about what size to choose, don't hesitate to ask a salesperson for help. With a little bit of guidance, you'll be able to find the perfect pair of compression socks for your needs.

How Do You Determine Sock Size?

Sock sizes are typically measured in inches, not by your shoe size. So, a sock size 6-8 will comfortably fit someone whose feet are between six and eight inches long. However, at FITS®, we make it easy for you to choose the ideal sock size without having to measure your foot. Simply use our sock size conversion chart based on your shoe size to select the right fit for you. 

How Do You Measure Your Foot for Socks?

To measure your foot for socks, measure the length from the heel of your foot to the tip of your longest toe. The measurement in inches correlates to your sock size. For example, if your foot is 10 inches long, a sock size 9-11 should fit you comfortably. At FITS®, you can skip this step and find your sock size based on your shoe size using our conversion chart. 

What Is the Sock Size Conversion?

The sock size conversion refers to sock size compared to shoe size. While all companies may vary slightly on which size socks to purchase based on your shoe size, you can always measure your foot to find the right fit for you. 

What is Sock Size to Shoe Size?

Because sock sizes are determined by the length of your foot in inches vs. your shoe size, shoe and sock sizes differ. The FITS® sock size to shoe size conversion is as follows:

Knowing this makes it easy to choose the ideal sock size based on your shoe size without measuring your foot. 

What Age is Sock Size 9-12?

Sock sizes typically don’t correlate with age. For kids, age can be a general indicator of what size sock they’ll need, but everyone is different. An adult sock size 9-12 fits anyone whose feet are approximately nine to twelve inches long. For kids’ sock sizing, check with the company to find exact details to ensure your little one gets the perfect fit.
